<div class=Section1>
<p class=MsoNormal>Hi there,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I'm experimenting with the DLR and IronPython and I've run
into a puzzling issue.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>1.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>I have a type (ObjectId) that implements
IDynamicMetaObjectProvider (written in C#).<o:p></o:p></p>
<p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo2'><![if !supportLists]><span
style='mso-list:Ignore'>2.<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>My derived DynamicMetaObjectProvider implements all the
plumbing so that ObjectId can be converted to IEnumerable.<o:p></o:p></p>
<p class=MsoListParagraph><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Given the above the following C# code works:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal style='text-autospace:none'><span style='font-size:9.5pt;
font-family:Consolas;color:blue'>dynamic</span><span style='font-size:9.5pt;
font-family:Consolas'> btr = <span style='color:#2B91AF'>ObjectId</span>.GetBlockTableRecord();<o:p></o:p></span></p>
<p class=MsoNormal style='text-autospace:none'><span style='font-size:9.5pt;
font-family:Consolas;color:blue'>foreach</span><span style='font-size:9.5pt;
font-family:Consolas'> (<span style='color:blue'>dynamic</span> o <span
style='color:blue'>in</span> btr)<o:p></o:p></span></p>
<p class=MsoNormal style='text-autospace:none'><span style='font-size:9.5pt;
font-family:Consolas'> o.Prop = <span style='color:brown'>1</span>;<o:p></o:p></span></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>HOWEVER, the following IronPython code fails:<o:p></o:p></p>
<p class=MsoNormal>-----<o:p></o:p></p>
<p class=MsoNormal>import clr<o:p></o:p></p>
<p class=MsoNormal>clr.AddReference("Dyn.exe")<o:p></o:p></p>
<p class=MsoNormal>import Dyn<o:p></o:p></p>
<p class=MsoNormal>for o in Dyn.ObjectId.GetBlockTableRecord() :<o:p></o:p></p>
<p class=MsoNormal> o.Prop = 1<o:p></o:p></p>
<p class=MsoNormal>-----<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The error I'm getting is this:<o:p></o:p></p>
<p class=MsoNormal>TypeError: iteration over non-sequence of type ObjectId<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Note that IDynamicMetaObjectProvider::GetMetaObject isn't
even called by the IronPython runtime in this situation.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Is this a bug? How can make IronPython query IDynamicMetaObjectProvider
in this case?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>For you reference here's all the C# code that implements
Dyn.exe:<o:p></o:p></p>
